      Lesson details

      Learning outcome

      I can use observable characteristics to classify plants in different ways.

      Key learning points

      1. Many plants have similar features that allow us to sort them into groups.
      2. Plants can be grouped by their observable characteristics.
      3. Observable characteristics can include information about colour, size, shape and structure.
      4. The process of grouping plants based on their similarities and differences is called classification.
      5. Plants can be classified into categories such as flowering plants and non-flowering plants.

      Keywords

      • Observe - To observe is to look very closely and use other senses too.

      • Groups - We put similar things together in groups.

      • Observable characteristics - An observable characteristic is a feature of a living thing that we can see or describe using our senses. We can use these to help identify it.

      • Classify - To classify is to sort objects into groups based on their similarities and differences.

      Common misconception

      Pupils may believe that all plants are green and have flowers.

      Clarify with a range of examples that some plants have flowers and some don't. Discuss with the pupils if they think even flowering plants will always have a flower on them all year round.

      Teacher tip

      Use real plants as well as the images on the slide deck. You could link to plants in other countries depending on what geography topic you may be teaching at the same time as this science unit.

      Equipment

      Access to secondary sources or the outdoors to find other plants.
